Zoom in of some Imrian countries

Yes, the oceans part is very realistic. But if two continental plates are colliding right at Imry sea that would be an area full of mountains, not a depression. Convergent boundaries must surround the sea (at least partially), not exist right on it.

I like the shape of the continents ^^ ... But I am much less picky and expert on tectonics to me they look good but listen to pixie sugestions he is the expert on that .

So the small plate that the sea is on would be subducting underneath the other two, larger plates that make up the main land masses?

Also, how far out from the coastline should continental plates go? Are they in the right place for the unnamed continent on the left side?

It doesn't have to be a small plate, it may just be a shallow part of one of the continental plates (sea Aral Sea, Caspian Sea and Black Sea for example)

It varies a lot. Compare the bathymetry of the coasts of Liberia or Chile with the US East Coast or Vietnam coast... you can pretty much place it anywhere.
